Asynchronous Events

A MIL-1553 receive application can register condition(s) to be monitored by the receive firmware.

When a callback handler is defined, the condition(s) are reported to the application asynchronously from the firmware to the handler.

The way to define a handler is as follows:

• Initialize the receive acquisition as usual.
• A callback handler must be registered using the mxfAsyncEventHandlerInit() function.
• The conditions to monitor must be defined using the mxfAsyncEventConditionsSet() function.

After this registration, the application can read acquisition data as usual and/or receive asynchronous events through the callback handler.

The receive queue can also be read from the callback handler if necessary.

List of conditions

The event conditions that can be monitored are as follows:

Condition	Description
MXF_ASYNCEVENT_COND_RXACQ_THRESHOLD	Acquisition buffer threshold exceeded.
MXF_ASYNCEVENT_COND_RX_MSG	Specific message available in the queue.
MXF_ASYNCEVENT_COND_RX_ERROR	Receive errors on the RX port.
